+ BVLGARI Vintage Tubogas 1990s Automatic 30mm 18-karat yellow, white and rose gold watch

BVLGARI’s ‘Tubogas’ watch is defined by its ribbed bracelet strap, which is inspired by the coiled metal coverings of gas pipes – to achieve the same effect, the steadiest of hands painstakingly assemble 18-karat white, yellow and rose gold bands that have been heated and molded around a wooden core. Part of Stephanie Windsor’s curated collection of vintage treasures, this 30mm model has a sleek black dial encircled by a logo-carved bezel. It remains in pristine condition and comes in its original box.
